Prediction of compressive strength of concrete using electrical resistivity measurement on cement and fine aggregate replacement
  R.K. Mishra and R.K. Tripathi
  Performance and reliability of any part or whole structural unit depends up on the pre and post quality or aging and degradation. This phenomenon can also be observed on performance of ingredients. The properties of concrete core or any cementitious sample can be related with its density or strength. An electrical method of testing involves passing electrical current perpendicular to casting direction [1]. This helps in finding out denseness or packing due to compaction and development of hydration product [2]. This paper deals with the correlation between concrete bulk resistivity using parallel plate resistivity meter, compressive strength test results and setting empirical relation for the same. The tests have been conducted in the laboratory by varying ingredients in concrete.
